As the chaotic scene continued in the nation's capital with the world watching, Trump once again tweeted his repeated his false claim that the presidential election was being stolen from him and appeared to try to justify the storming of the U.S. Capitol that he encouraged earlier in the day.

"These are the things and events that happen when a sacred landslide election victory is so unceremoniously & viciously stripped away from great patriots who have been badly & unfairly treated for so long," he said.

"Remember this day forever!" he added.

Former President George W. Bush released a statement on what he called an "insurrection" at the U.S. Capitol, calling it "a sickening and heartbreaking sight."

"This is how election results are disputed in a banana republic – not our democratic republic. I am appalled by the reckless behavior of some political leaders since the election and by the lack of respect shown today for our institutions, our traditions, and our law enforcement," Bush said.

"The violent assault on the Capitol – and disruption of a Constitutionally-mandated meeting of Congress – was undertaken by people whose passions have been inflamed by falsehoods and false hopes. Insurrection could do grave damage to our Nation and reputation. In the United States of America, it is the fundamental responsibility of every patriotic citizen to support the rule of law. To those who are disappointed in the results of the election: Our country is more important than the politics of the moment. Let the officials elected by the people fulfill their duties and represent our voices in peace and safety," Bush continued.

He did not mention President Trump by name.

Ahead of the district-wide curfew, the entire D.C. National Guard, FBI Washington Field Office, U.S. Secret Service, Federal Protective Services and the Metropolitan Police Department are responding to the breach at the U.S. Capitol to assist Capitol Police, sources tell ABC News. Deputy U.S. Marshals are also being deployed to assist, according to a Justice Department official. Customs and Border Protection officers are being deployed as well.

Washington, D.C., Mayor Muriel Bowser issued a curfew beginning at 6 p.m. and ending Thursday at 6 a.m. earlier in the day -- but with minutes to go until that curfew, there are hundreds of pro-Trump supporters still on the streets, resisting calls from law enforcement and lawmakers to go home.

After nearly four hours of pro-Trump supporters breaching the building, officials have declared the U.S. Capitol is secure.

Here are images of what’s unfolding:

Sen. Joe Manchin, D-W.V., just told reporters on Capitol Hill that the Senate intends to finish certifying the election this evening.

"We're going to finish tonight," Manchin said. "Everyone is committed to staying whatever it takes to get our job done."

"These thugs are not running us off," he added.

Manchin told reporters he believes that they will be able to continue debate in the Capitol building.

He said that being in the secure holding room with other Senators had a "way of bringing us together."

Trump has been quiet Saturday after Twitter announced Friday evening that it had permanently suspended the president's account.

"After close review of recent Tweets from the @realDonaldTrump account and the context around them -- specifically how they are being received and interpreted on and off Twitter -- we have permanently suspended the account due to the risk of further incitement of violence," Twitter wrote in a statement.

Trump's final tweet said he would not be attending Biden's inauguration.

After Twitter's announcement, Politico reported that the president went "ballistic" and “[scrambled] to figure out what his options [were].”

Hours after his suspension, Trump released a statement criticizing the ban and teasing a possible new platform.

"I predicted this would happen," he wrote in part. "We have been negotiating with various other sites, and will have a big announcement soon, while we also look at the possibilities of building out our own platform in the near future. We will not be SILENCED!"

"Twitter is not about FREE SPEECH. They are all about promoting a Radical Left platform where some of the most vicious people in the world are allowed to speak freely," he added.

Trump had attempted to post the same statement on Twitter using the official @POTUS account, but the platform deleted the thread, saying users who are banned cannot post from other accounts.

Secretary of State Mike Pompeo blasted Twitter Saturday, comparing the ban of the president to something that would happen in China.

"Silencing speech is dangerous. It’s un-American. Sadly, this isn’t a new tactic of the Left. They’ve worked to silence opposing voices for years. We cannot let them silence 75M Americans. This isn’t the [Chinese Communist Party,]" he wrote on Twitter.

Former Ambassador to the United Nations Nikki Haley also took to the platform to draw a comparison to China writing, "Silencing people, not to mention the President of the US, is what happens in China not our country. #Unbelievable"

The White House announced Thursday that the president planned to spend the weekend at Camp David before notifying reporters that the trip was canceled. The president has nothing on his schedule Saturday.
